Powering and maintaining your camera 53
Caring for your camera and
accessories
Camera
Keep the lens clean to help you take sharp, clear photos with
the best possible focus. Use a dry, soft, lint-free cloth to gently
wipe the lens and status and image displays to clean off any
fingerprints and dust.
Wipe the outside surfaces of the camera with a clean, dry
cloth. Never use a rough cloth or abrasive cleaners, which can
scratch the camera.
Do not leave the camera in the sun or in a very warm location
(for example, inside a car) for long periods.
If you move the camera from a cold to a warm location or vice
versa, always allow the camera several minutes to adjust to the
current ambient temperature before you use it.
Memory cards
To avoid erasing data from a memory card or damaging the
card, do not expose it to heat, moisture, or static electricity.
